Fractional CTO 💡 Top Startups Voice⚡ Helping startups make better SaaS

I'm an experienced SaaS CTO, working on a 'Fractional' basis, meaning that companies can hire me part-time as their Interim CTO, or as an advisor to the board. 

I work for startups, scaleups, ISVs and other software companies, or consultancies turning into SaaS companies.

My work is transformational: when I leave, a company should be better off in terms of their (tech) strategy and/or operational excellence.

Before becoming a CTO, I have been a solutions and cloud architect. I still code, as an open source contributor, and sometimes for 'my' startups, doing Proof-of-Concepts.

I'm a Web Standards evangelist, and a Social Impact Lover. 

I've seen it all, with more than 30 years of experience in Software Development, and I'm now focusing on Native Cloud as a natural fit for startups and scaleups.

I write a lot about the life of a CTO, and about the Modern Web.

Financial forecasting is van groot belang. Voor toonaangevende ondernemingen is een betrouwbare voorspelling een essentieel onderdeel in hun streven naar waardecreatie. Het management gebruikt deze voorspellingen om de prestaties te stimuleren, kansen en risico's te identificeren en als basis voor communicatie met stakeholders zoals aandeelhouders. Zonder betrouwbare forecasts is de kans groot dat belangrijke kansen en risico's worden gemist.

Ondanks de aantoonbare voordelen van accurate forecasts blijven veel organisaties echter worstelen met dit bedrijfskritische proces. 2ACC3L helpt je hierbij. Of je nu een start-up bent, of een bedrijf dat al tientallen jaren bestaat, of je een high-tech onderneming bent of dat het geld wordt verdiend met traditionelere producten, wij ondersteunen je bij het opstellen van een forecastmodel dat geschikt is voor jouw specifieke situatie.

Founder | Revenue forecasting & insights | Get your revenues up with RevsUp

I’ve spent over 20 years as a financial professional, building countless budgets and forecasts. But as anyone in finance knows, the struggle is real—especially when it comes to forecasting accurately and having those frustrating back-and-forth discussions with sales.

For years, Excel was my go-to tool. I’ve logged more hours in Excel than I’d care to admit. But after one too many crashes, I realized: Excel is great for many things, but financial forecasting isn’t one of them. It’s just not built for real-time collaboration, data integrity, or handling large datasets without falling apart.

That’s when the idea for RevsUp was born. I couldn’t find a tool that did what I needed—so I decided to build one. RevsUp is a user-friendly SaaS platform that helps businesses create smarter forecasts and gain actionable insights. No more endless Excel updates, no more guesswork—just accurate forecasts that help drive predictable revenue.

If any of this sounds familiar and you’d like to chat, feel free to connect with me. Or follow me for more insights on revenue forecasting!
